Abstract: Aiming at the matching and intersection of multiblasting point data tested with video theodolite in conventional ordnance test, it offers an entire set of analyzing data techniques. Firstly we made the allcombination intersection calculation with the angle data from each testing station to obtain the collection of coordinate data of many possible blasting points. Then we set the distance threshold value according to the near neighbor rule to get rid of the majority of fake objections by clustering method, and retained the possible blasting point collections closed to the target. Thirdly we processed the preliminary blasting points collections with matrix analysis based on the evidence theory. Eventually we got the collection of the coordinate data of blasting points. Simulation and experiment results show that the method can effectively process the angle data of no more than 10 ground exploding point targets with the same frame, and get the coordinates.
